But Tottenham have worked hard over the last 48 hours to conclude the deal, convincing Davies to join the club with the promise of a regular starting place.

The deal was also smoothed by the fact that Spurs and Swansea are both on pre-season tours in the United States and have been in extensive talks, while there is a strong relationship between Tottenham executives and Davies's representatives.

Davies will become the first signing for the Londoners under new manager Pochettino, who oversaw a 3-3 draw with MLS side Seattle Sounders on Saturday.

Swansea are hoping to sign midfielder Sigurdsson in an £8m deal to improve their attacking options ahead of the new season.

Crystal Palace are also trying to sign Sigurdsson but the 24-year-old has indicated that he wants to take his time and assess his options.

Sigurdsson spent the second half of the 2011-12 season on loan at the Liberty Stadium, scoring seven goals in 18 Premier League appearances for the Welsh club.
